Quick Links
InPalworld, reaching some locations can be a challenging task. This is because each island in the game hosts Pals with variable levels. Higher-level Pals can pose a significant danger to you and your team. Additionally, the geographical conditions of the islands should also be considered.
Furthermore, traveling in some areas becomes impossible due to cold and hot climates on certain islands. Fortunately, you can craft armor to address this issue. How about wearing an effective accessory in this regard? With the Multiclimate Undershirt, neither heat nor cold will be your enemy.

How To Get The Multiclimate Undershirt
You cannot findthe Multiclimate Undershirt anywhere in the game. Additionally,you cannot craftthis accessory in any way. The only way to obtain it is bydropping it from one of the Raid Bosses in the game, Bellanoir,or its challenging version, Bellanoir Libero.
Since Bellanoir Libero is quite challenging, you should obtain this item from Bellanoir.

To do this, you must firstreach level 33 and then build a Summoning Altarin one of your bases. The materials required for the Summoning Altar are as follows:
100

Paldium Fragment
20
Since you need to summon Bellanoir to your base using the Summoning Altar, you shouldbuild it in a base where you are not actively using it.Otherwise, your structures may be damaged and destroyed during battle.

Next, you need toobtain four of Bellanoir’s Slab Fragments from dungeons.However, these fragments do not drop from every dungeon. Therefore, you must go to specific dungeons:

After obtaining four Bellanoir’s Slab Fragments, you shouldcombine them on a crafting table to obtain the Bellanoir’s Slab.Alternatively, you may also combine the fragments of Bellanoir Libero in the same manner.
From this stage onwards, what you need to do isequip yourself with powerful armor and good weapons.
Additionally, it would be logical to have Dragon-type Pals becauseDragon-type attacks deal significant damage to Bellanoir, who is of the Dark type. Also, as it will participate in the battle,maximize the level of your battle base. Then, place 15 powerful Pals, preferably Dragon-type, in your base.
You have ten minutes to defeat Bellanoir, and it has a total health of 340,000.
After defeating Bellanoir, among the battle spoils, you will find the Multiclimate Undershirt.
Multiclimate Undershirt Ability, Explained
As the name suggests, when you equip the Multiclimate Undershirt as an accessory,it protects you from both cold and hot climates.
You may already know that locations like the Dessicated Desert, Mount Obsidian, and Astral Mountains are challenging to navigate due to their harsh climates.Equipping this item in your accessory slot ensures that you are not affected by these conditionsin any way.
You will eventually want to reach these mentioned challenging locations. The reason for this is thepresence of unseen Pals and resources like Coal and Sulfur,which are essential for late-game progression. Additionally, three of the Pal Tamers (tower bosses) are also located in these regions.
The Heat Resistant Undershirt and Thermal Undershirt are also items that protect you from cold and heat when used as accessories. However, equipping both of them occupies two inventory slots. Therefore, the Multiclimate Undershirt is a more sensible option asit only occupies one slot.

Heat Resistant Level One
Additionally, your Heat or Cold Resistancemay not be sufficient in some situations.For example, if you ride a Vanwyrm on Mount Obsidian, a level one Heat Resistance will not be enough. In this case, wearing items that provide more climate resistance will be beneficial for you.
